Werder, Lakewood, Ohio,` assignor of onehalf -to Edmund Rogers, South Euclid, Ohio Application December 1, 1933, s'eriiNo.. 700,624 -9 claims. (crisi-215 This invention relates to an improved form of supporting base fora fluid container and ajvalve structure for dispensing the contents thereof.

The present invention is Vespecially adapted for use in dispensing Va lubricant charged with inert gas, as for instance carbon dioxide, -but its use is not limited to this particular liquid.

One object of the present invention is to devise a compact and conveniently arranged combina- '1 tion of supporting base and valve structure to which the fluid container may be attached for discharging purposes.

Itis also the objectof my invention to devise a valve structure in which the parts are so formed andassembled that it is proof against leaking at any point thereof. Y

Other objects will appear from the following description and claims when considered together with the accompanying drawing K Figi is a vertical sectional view of my inrproved device; g Y

Fig. 2 is an enlarged view rof a portion of the valve structure as shown in Fig. l; and

Figs. 3l and 4 are taken on lines 3-*3 yand 4 4, respectively, of Fig. 2.A y y It is to be understood that the present 'disclosure is merely for purposes of illustration and that various modications may be made without departing from theV spirit of the present invention as herein set forth and claimed.

The supporting base'has the legs I, three or more in number, which are slightly inclined and within the central part of which there is arranged the valve structure.

The Valve structure, considered as a who1e,'is of an inverted T-shape as will be seen from the drawing (Fig. 1), and comprises a one-piece L- shaped member to which another member .is attached. y. The vL-shaped member has Nthe vertically disposed tubular arm '2 and the Yhorizontally disposed tubulararm 3. TheL-shaped member `lis'either formed integrally with the supporting `base vor maybe suitably secured thereto.

' The arm 2 is screw-threaded upon the outside thereof and is adapted to receive the screwthreaded nozzle 4 which is affixed to the container 5. The'inner end of the nozzle 1i Yhas the iiange 6 surrounding the opening I which is closedlby a 50 rangible seal prior to theV attachment of the container tothe valve structure. This seal is adapted to Vbe broken by t'he'projectingl end portion 8 of thel member which is .adapted to be engaged between the upper end of the'arm Zand the ange 55.*: E. This member has a portion 9 extendingwithin the passage :ofthe .arm 2 landhas ashoulder for engagement with the. upper fend of the arm 2 while its conical surface I0 is adapted for sealing engagement with the outer annular edge of the ange .E Vabout the opening 1. Either or both of these interengaging members 'are formed of semisoftmetal so as ,to vpermit an effective sealing seat to beformed between .the edge of the ange 6 and the conical surface Illl when the parts are brought into engagement.

The member which; is employed to break the seal `over the opening 1 has a passage I I extending longitudinally therethrough and has also the transverse passage 4I2 communicating with the other passage IjI, so thatY the broken seal disk will not prevent discharge of the contents.

The outlet arm `I3 has screw-threaded engagement with the L-shaped member and extends in alignment withthe arm 3,. The arm I3 has a shoulder and seat engagement at the point I4 which is located upon the opposite side of the passagein Vthe arm-Z, that is, between the passages ,in/the arms 2 and 3. The arm I3 has also ayshoulder and seat engagement upon the outside ofthe I --shaped member, as indicated at the point I5. Either the L-shaped member or the member I3, or both fofV them. may be .formed `of semi-soft metal, and `the distance v.between the shoulders I4 v.and ,I5 of the arm I3 may be the same as that between the corresponding seats, in whichY event, therewill be effected sealing en-` gagements at the two points at the same time. However, it is preferred that the distance between the .shoulders I4 `and =I5 of the arm i3 be slightly greater than that between the cor-responding seats, so that upon screwing the arm into assembly, the surfaces at I4 may rst form an effect-ive .sealing-engagement by virtue of the yieldingnatureyof the metal, and then a sealing engagement xmayalso be formed `at .I5 upon further screwing the arm I3 intoassembly.,

. The inner end portion of thearm -Iv3is spaced from the wall of Ythe L-shapedinember and has a diametric ally disposed passage I6 which in turn communicates with the vlongitudinally extending passage I1, the end Aof which affords aseat for the needle `valve I8 formed on the end of valve stem I 9.- The valve vstemrl9 extends through the tubular arm 3 and has the vpacking 20 and isV screwthreaded into the end of the arm I3, with the result that the conical surface o t :the valve I8 has a line contact with the annular edge about the end of passage `l 1. Either or both Yof the member 13 and the valve .18 Y[maybe formed of semi-soft metal so as to permit an eiiectivesealing engageprovided any desired form of manually operatable:y valve for readily dispensing the lubricant or other iiuid from the container after-the lvalve I8A` has been opened.

Upon discontinuance of use of theldisr'charge device, the valve I8 will iirst be closed and the tube 23 will be permitted to drainbeforel 'closing1v the valve on the outer end thereof. Thenmthere.. is precluded any danger of discharge of the 'ma--V terial as might otherwiseoccur .upon accidental opening ofv the valve' on the outer end ofthe tube.23. :J

Also, the seal at the point *I4 prevents the lubricant or other liquidiin the container from reaching the packing 20 and consequently leaking therethrough asI might otherwise happen.

As indicated in the drawing, the arms 3 and I3 constitute what might be recognized as the head of the inverted T-form of .valve structureand the arms 3 and I3 are confined substantially within the limits of thelegs I of the supporting base. Y '-f vThe entire assembly may be carried by the handle 24 which is mounted in the bracket-w25. These brackets continue as straps 26 about the bodyjof the spherical-container V5 and are pivotally `mounted upon the supporting base. The wing nut ZI is applied to the one end ofthe bolt 23 whichextends through the upper ends of the brackets and through the handle so as to maintain these parts in assembly. Upon disassembly of these parts,.an empty container canY be re'- moved and a fullone-substituted b'yvscrewing its nozzle 4 onto the threadedV arm 2A in the manner above referred to. u Thus, I-have. devised a compact form or structure whichl can be conveniently handled Aand employed and in which all pointsfo'fv connection in the valvestructure are `eiectively sealed against leakage, The -sealing of Vvthe valve structure at all pointsof connection is especially importantin the dispensing of gas-charged lubricant `because of the fact that the .lubricant is discharged under the pressure of the gas which is liberated fromthe gas-charged lubricant itself upon initiation of andduring the discharging' operation;v but this structure may be employed with other liquids,v as well and the following claims are not tofbe understoodl as being limitedin this respect.-
